The pri- The wings l5 and I8 ofadjacent cup portions mary purpose of the present invention is to prol3are joined to one another by fold portions provide trays which may bemade from sheet mavided with score lines 22 which form ridges beterial,suitably cut and set-up, to form a paper tween adjacent cups when theblank is set up, as

or the like employed in making ice cubes. The wings l6, iii of adjacentcup portions are With the foregoing object outlined and with joined toone another by strip portions 23 having 16 1 other objects in view whichwill appear as the score lines 24 extending longitudinally of thedescription proceeds, the invention consists in the middle portionthereof, and these strip portions novel features hereinafter describedin detail, are joined to the wings I6, l6, along fold lines 25.illustrated in the accompanying drawings, and When the blank is set upwith the wings H5 at more particularly pointed out in the appendedangles to the strip portions 23, those portions are 20 claims.preferably folded or curled as indicated at 26, in

In the drawings: Fig. 3, to form a ridge extending lengthwise of Fig.lisa plan view of a portion of a blank of the tray, and which may betorn by tearing along paper or the like designed for use in making thethe score line 24. A tonguei2'l forms an extension Referring to thedrawings, it will be underposite ends, one of said tongues being adaptedto stood that the tray may be formed of any suitbe secured to the flangeand the other to one able destructible sheet material such as.waxed' ofthe tongues2l, soas to form a flange 33 at paper, so that parts thereofwill adhere to one each end of the tray.

In the embodiment of the invention illustrated and the flaps 20 will becaused to adhere to the in Figs. 1 to 3 inclusive, 8 designates a blankof outer surfaces of adjacent wings, as indicated in at intervals alongthe longitudinal 'central-porcaused; to overlap adjacent strips 23, andthe tion thereof, and provided at its opposite longitongues 21 at theends of the blank will be caused tudinal edges with notches l0, eachpair of to adhere to opposed ones of the tongues 32. notches being inlateral alignment with one of Simultaneously, the tongues will be causedto the apertures 9. A notch II is arranged at each overlap adjacentstrips, and the tongues 29 at the 50 end of the blank inlongitudinal-a1ignment with ends of the .blank will be caused to overlapand the openings 9, and other-notches [2 are located adhere to certainof the tongues 32. Finally, the at the corners of the blank. The uncutportions continuous strip which has been formed by the of the blank formportions l3 of Maltese cross strip portions 23, may be curled to formthe ridgeshape; each portion l3 preferably having 0. rec- 26. I

If the tray is not formed of wax paper, but of some other suitable plainpaper, of course, an adhesive will be placed on the blanks at thenecessary points to cause adherence of overlapping parts. Finally, suchtray will be coated with paraflin or the like to allow water to beintroduced into the cells 2|.

After ice cubes have been formed from water placed in the cells, thecells may be torn from one another along the score lines 22 and 24, andin this way one or more cubes may be removed from the tray withoutaffecting the cubes in the remaining cells. In Fig. 1 it will be notedthat the portions l3 are cut at 35 all the way into the corners of thebody portions l4 so that each flap 2!! extends throughout the entireheight of the wing with which is merges. To eliminate any possibleleakage which might be caused by manufacturing in this way, I may alterthe structure as indicated in Figs. 4 to '7 inclusive. For instance, inFigs. 4 and 6, each flap 20a, instead of being the full width of thewing to which it is attached, may terminate as indicated at 35a, shortof the body Ma, so as to form a short plait 36 when the blank is set up,as indicated in Fig. 6.

Instead of using the flaps at all, I may leave substantially triangularportions 201) between adjacent wings, whereby when the blank is folded,such portions 20b will form plaits 200 at the corners of the cell, eachplait being of substantially the same height as the cell.

While I have disclosed what I now consider to be preferred embodimentsof the invention in such manner that the same may be readily understoodby those skilled in the art, I am aware that changes may be made in thedetails disclosed, without departing from the spirit of the invention asexpressed in the claims.
